Ellipsoid¶

Type:	section
Appearance:	multiple

Adds the ellipsoid region

$\begin{eqnarray*} \sqrt{\left(\frac{x-x_c}{d_x/2}\right)^2 + \left(\frac{y-y_c}{d_y/2}\right)^2 + \left(\frac{z-z_c}{d_z/2}\right)^2 } \leq 1 \end{eqnarray*}$

to the core region, where $[x_c, y_c, z_c]$ (Center) is the center and $d_x$ , $d_y$ , $d_z$ are the diameters of the ellipse in the three coordinate direction (Diameters);
